Solaris Practice-2 [ zones ]

PRACTICE WORK-SHEET-2 [zones]

Well, learned Zones?

OK…

Now time to have some Practice to check How Frequently or without looking to our notebook we can solve the things OR how much command we have on the Topics.

1.  What is zone?

2.  What are the types of zones?

3.  List some benefits of zones?

4.  What is Global zone & Non Global zone?

5.  What are the types of NGZ?

6.  What is diff between whole root zone & sparse root zone?

7.  What is zonepath?

8.  List & define the daemons & their functions for zones?

9.  Is it possible to assign different types of file systems to NGZ? If yes then what is the procedure to do so.

10. What are the zone states? Define all

11. How to assign physical disk to NGZ?

12. What are the IP management schemes available in zones? Define with         example

13. What is difference between zone login and zone console login?

14. How to do console login to NGZ?

15. How to add the extra IP to NGZ?

16. How to rename the NGZ?

17. How many NGZ created in one GZ?

18. Where the zones config files stored? [/etc/zones/<zone-name>.xml]

19. Which file has zones current config state? [/etc/zones/index.xml]

20. How to check the zone is global or non-global?

There is a hit & run method to know this, run the “dladm show-dev” cmd Wherever it runs mean GZ, & where throw error its NGZ… hohoho hihihi …. What? It’s true; ok don’t like this… no prob

I have one more tech solution of this; have heard “pkgcond” cmd?

Ok… no issues, just man it.

root@sol-test-1:>/# pkgcond is_nonglobal_zone

root@sol-test-1:>/# echo $?

1

So what was that? I was asking to sol-test-1 that is this nonglobal zone? And by echo$? I checked the status of exit_code & it is 1 (unsuccessful) means no it is not NGZ,

Let’s check this again by asking about GZ

root@sol-test-1:>/# pkgcond is_global_zone

root@sol-test-1:>/# echo $?

0

Hurrraaaah, this is GZ

21. How to check the zone is whole root or sparse root?

We can check this also by two methods

One is as above mentioned

root@sol-test-1:>/# pkgcond is_whole_root_nonglobal_zone

root@sol-test-1:>/# echo $?

1

This way we need to login in zone and then run the cmd, otherwise we can

root@sol-test-1:>/# zonecfg -z tzone4 info |grep -i inherit

There is nothing in o/p, means it is whole root zone

root@sol-test-1:>/# zonecfg -z newzone info |grep -i inherit

inherit-pkg-dir:

inherit-pkg-dir:

inherit-pkg-dir:

inherit-pkg-dir:

This is sparse root zone

22. How to boot/reboot/halt a zone?

23. What are common resources available for NGZ’s?

24. What is rctl?

25. What is the process to delete a zone?

Halt à uninstall à delete [if required use –F option]

26. How to control the resources in NGZ?

27. How to boot NGZ in single user mode?

28. How to check the process statistics of NGZ’s?

29. How to check the disk utilization of NGZ’s?

LAB WORK

30. Create a simplest NGZ sparse root zone “testz1” with shared ip

31. Install & boot the testz1 also check zone state after each step

32. Console login to testz1 and complete the installation

33. Add a lofs FS in testz1

34. Add a device “tape” in testz1

35. Add a disk from GZ to NGZ testz1

36. Add a zfs dataset to testz1

37. Add an additional ip to testz1

38. Add attributes like name—department—phone no in testz1

39. Mount a dir /testdir from GZ to NGZ testz1 without rebooting NGZ

40. Add 1 cpu to NGZ testz1

41. Remove the recently added cpu

42. Again add cpu with range 1-2 to NGZ testz1

43. Add physical memory=200mb,swap=100mb,lock the mem to min 100mb in testz1

44. Remove the cpu setting

45. Add the cpu share of 30% to testz1

46. Increase the phy mem temporarily by 400mb in testz1 without reboot

47. Increase the swap to 256mb in testz1 without reboot

48. Check the rctls of testz1 from GZ

49. Check all zone related available rctls

50. View the config file of testz1

51. Remove all FS, devices, cpus, memory, swap….. from testz1

52. Delete the testz1

53. Create another NGZ testz2 with size limitation of 1gb

54. The ip setting for testz2 will be exclusive

55. Add a ufs /testdir to testz2

56. Move this zone to /export/zones/newzone

57. Add a zfs dataset to this NGZ newzone

58. Migrate the newzone to other solaris system and boot there

59. Rename the newzone to testz3

60. Change the hostname/ip of testz3

61. Clone the testz3 and create new NGZ clonedzone1 from the clone of testz3

62. Create a whole root zone testz4 

63. Check the resources on all zones from GZ   [prstat –Z]

64. Try to find the files greater than 100mb on testz4 from GZ

65. Renice the find process to -19 from GZ

66. Check all running services of testz3 from GZ

67. Find the processes on tetsz3 from GZ   [prstat –z testz3]

68.
